Problem 5: A medical facility does MRI scans for sports injuries. Occasionally a test yields inconclusive results and must be repeated. Using the following 10 sample results for the number of retests in n = 220 observations each, determine the control limits for the proportion of retests using three sigma (standard dev) limits. Is the process in control? Why/why not?e [5 Marks] Sample: Number of retests. 2 5 loee le Bonus Question: A lower sample range value implies that the variability is less, which is desirable. What is then the point ofhaving a lower control limit for range values? [1 Bonus Mark overall assignment marks cannot exceed 100%]
